Subject field(s)

DEF

A clear solution of resinous material or natural gum, such as copal or rosin dissolved in acetone, ether or chloroform, that is capable of hardening without losing its transparency. Used in cavity preparations to seal out dentinal tubules, to reduce micro-leakage, and to insulate the pulp against shock from thermal changes.

OBS

"cavity liner": Often treated as synonymous with "cavity varnish". "Cavity liner", however, may designate a calcium-hydroxide or zinc-oxide material used to provide a lining in deeper cavities, as well as the varnishes used for more shallow cavities or tooth breaks.
